Metal oxide is the ionic bond combination of any metal element of the Periodic Table of elements with oxygen. The alkali metals and alkali earth metals are respectively the first and second columns of elements found on the periodic table. Thus, alkali metal oxides and earth metal oxides are types of metal oxides, but metal oxide does not imply alkali.
Alkali
Metal oxides are bases.So calcium oxide is also a base or alkali.
Copper oxide is not an alkaline but it is a base
No potassium OXIDE is not: IT IS A METAL. IT IS A METAL.And it is not a NONmetal either.Potassium OXIDE K2O is a basic oxide: with water it forms (only) potassium hydroxide, KOHPotassium (elemental) is a alkali metal
sodium oxide (solid) is NOT an alkali. sodium oxide forms sodium hydroxide (aqueous) is an alkali. so sodium oxide becomes an alkali only when in aqueous form and in aqueous form it is called sodium hydroxide.

It is strongly basic as it is an oxide of an alkali metal.
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
An amphoteric metal oxide is the oxide of a metal that can form either simple metal cations or oxyanions, depending on reaction conditions. If zinc oxide is reacted with a stong acid, a simple zinc salt including the anion of the reacting acid will form. In contrast, if zinc oxide is reacted with a strong alkali, a zincate salt containing the anion ZnO2-2 along with the cation of the strong alkali will result.
A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
